Objectives

  • To study the characteristic frequency of uncoupled pendulum.
  • To study the normal modes and resonance of coupled pendulum.
  • To determine the spring constant of coupling spring.
  • To calculate the time period of coupled pendulum when
    • a. Vibrate in phase mode (T0)
    • b. Vibrate in out of phase mode (T1)
    • c. Vibrate in couple mode (TC)
    • d. Beat period TB and beat frequency (FB)
    • e. To determine the degree of coupling.
